Fischer Disappoints!?

     The year 1959 was an interesting one. According to Rod Serling there was a fifth dimension we didn't know about...the dimension of imagination. It was an area known as The Twilight Zone, a mix of horror, science-fiction, drama, comedy and superstition; Serling was the program's narrator. The wildly popular program first aired in October, but we never watched it at our house; my dad didn't like it.
     The most famous person in the country was probably Elvis Presley, but February 3rd came to be known as The Day The Music Died. On that date rock and roll musicians Buddy Holly, Ritchie Valens and The Big Bopper (J.P. Richardson) died in a plane crash near Clear Lake, Iowa, along with the pilot, Roger Peterson. 
     They weren't the only celebrities to meet a violent death. George Reeves, who played Superman on television, died at the age of 45 from a gunshot to the head. He was found in the upstairs bedroom of his home in the wee hours of the morning on June 16, 1959. The official finding was suicide, but some believe that he was murdered or the victim of an accidental shooting. 
      The scandalous book Lady Chatterley’s Lover by D. H. Lawrence was creating a hubbub. Although it was first published in Italy in 1928, it was banned in the U.S. (and other countries) as being obscene. 
     The ban on it and another book, Tropic of Cancer, was overturned in court in 1959. According to a columnist with The New York Times, the ruling was going to set off an explosion of free speech. 
     In 1959, the first house with a built-in bomb shelter was shown in Pleasant Hills, Pennsylvania. Later, in October of 1961, President Kennedy advised American families to build bomb shelters to protect them from fallout in the event of a nuclear attack by the Soviet Union. Kennedy also assured the public that the country's civil defense program would soon begin providing shelters for every American. 
     It was just a year later that the world hovered on the brink of nuclear war when the Cuban Missile Crisis erupted over Russia's placement of nuclear missiles in Cuba. During the 13-day crisis, some Americans prepared for nuclear war by buying up canned goods and completing last-minute work on their backyard bomb shelters. 
The Blogmeister in younger days
     Speaking of Cuba, several years later, in 1964, on the 5-year anniversary of Fidel Castro's takeover of Cuba, I was with the Marine Corps and we were aboard an old WWII aircraft carrier loaded with helicopters that was circling off the coast of Cuba. We sat on deck all day with the helicopters running and shutting down only to refuel. We had been issued ammunition and our weapons were loaded as we were ready to board the choppers and be flown to the fence line at the Guantanamo Bay Naval Base in case the Cubans tried to invade the base. Nothing happened and towards evening we were told to stand down. 
 
       In testimony before congress, game show contestant Charles Van Doren admitted he had been given the answers and coached on his on-camera performance while appearing on the game show Twenty-One. 
     As a result, Congress added a law to prohibit the fixing of televised contests of intellectual knowledge or skill and quiz shows disappeared for a long time. 
     Bobby Fischer played in three tournaments in 1959. In Mar del Plata he tied for 3rd with Borislav Ivkov a half point behind Miguel Najdorf and Ludek Pachman who tied for first. Then, after an appearance in a tournament in Santiago, Chile, he tied with Paul Keres for 3rd in Zurich behind Mikhail Tal (1st) and Svetozar Gligoric (2nd). 
 
     The second Torneo de Arturo Alesandri Palma was held from April 20th to May 6th, 1959 in Santiago, Chile. According to a brief report in Chess Review, the sixteen year old Bobby Fischer's result was disappointing. Fischer, who was just beginning his international career, scored as many wins as Ivkov and Pachman, but he lost four games. Here is his win against the 1958 Chilean champion.

Unheralded Players, Forgotten Tournaments

     In his early days Fred Reinfeld wrote some excellent chess books, but they didn't sell so he took to writing junk, a trend not a few chess authors today have followed, and it made him a comfortable living. 
     One characteristic of a lot of Reinfeld's chess books was that he neglected to give details about the game such as the date, tournament and names of the players! 
     The following game is an example, but at least we know the names of the players and since the game was published in January, 1943, no doubt it was played in 1942, but the tournament was not given. 
     The player of the white pieces was given only as "M. Fish" while black was played by "S. Rubinow", who we know was Sol Rubinow, a Master who was born in New York City on November 6, 1923 and died on February 22, 1981. 
     It’s difficult to say exactly how good Rubinow was because his heyday which was before there was a rating list. However, after the advent of the rating list, he became a Life Master. When the USCF published its first rating list in November of 1950, Rubinow was rated 2243, which at that time was considered "Expert", not Master. 
     Chess was not his only interest. He was also a master bridge player and he became very prominent at his job...he was an authority on biomathematics, which employs theoretical analysis, mathematical models and abstractions of living organisms to investigate the principles that govern their structure, development and behavior. That's opposed to experimental biology which deals with the conduction of experiments to prove and validate the scientific theories. I hope that clears up any questions about Rubinow's day job. 
     Beginning in 1964, Rubinow was a professor of biomathematics at the Cornell University Graduate School of Medical Sciences. He was noted for research and papers papers on cancer research. 
     In 1943, he was intercollegiate chess champion. In 1952, he won the Massachusetts State Championship. He also took part in several U.S. Championships. 
     Dr. Rubinow died at the age of 57 at the Memorial Sloan-Kettering Cancer Center after having been hospitalized for two months following complications resulting from brain surgery. 
     Alas, the master Rubinow managed to lose to Fish in the following short, sharp, exciting game. It was, as Reinfeld stated, a fascinating game, but it was not the lopsided beating that he insinuated.

Tal at Jurmala 1985

 
     Jurmala?! It's a resort city in Latvia just west of the capital, Riga. It’s known for wooden art nouveau seaside villas, Soviet-era sanatoriums and long, sandy Jurmala Beach. 
     Starting in mid-August back in 1985, the 2nd Jurmala International Chess Tournament was played. Six of the 14 players were living in Latvia and the other eight had not played in Latvia before. 
     Hungary was represented by its 1983 champion IM Tamas Utasi, Bulgaria by GM Ventzislav Inkiov, Denmark by IM Carsten Hoi, the Philippines by IM Andronico Yap and England by IM Daniel King. 
     The Latvians were headed by Mikhail Tal. A talented young player named Alexander Shabalov was also playing. In 1991 Shabalov found his way to Pittsburgh, Pennsylvania and became one of the top players in the US for a while. He won the US Championship in 1993, 2000, 2003, 2007 and won or tied for first place in the US Open in 1993, 1999, 2003, 2007, 2008, 2015, 2016. 
     According to GM Daniel King, "...for much of the tournament Tal cruised along, not giving the chess his all; instead he was enjoying relaxing with his wife and young daughter." 

     In the last round Tal could share first place if he beat Danish IM Carsten Hoi and according to King, "Hoi didn't stand a chance. Tal was gunning for him." King described Tal's intense concentration and told how he "lit up a cigarette, sucking in the nicotine as though it were his life-blood, but never averting his gaze from the chessboard through the whole operation."

Reshevsky Shows How It's Done

     I had two favorite players. The first was Botvinnik and his book One Hundred Selected Games was a constant companion. Then I came into possession of Reshevsky On Chess and I had a new favorite player. I don't know why, but his games always intrigued me. His play looked so simple and logical that it seemed like I could duplicate his style. I couldn't of course, my 50 percent score against him notwithstanding. (We drew a postal game in 1979.) 
     During 1956 and 1957, Bobby Fischer had been playing a lot and by the time the 1957/58 championship rolled around most players felt was Reshevsky was the favorite although Larry Evans was also considered a contender while William Lombardy and Arthur Bisguier were not without their chances. Also, Robert Byrne was considered a possible contender, but he declined his invitation at the last minute.
     Going into the last round Fischer had 10 points and he met his old blitz partner, Abe Turner, and played an 18-move draw. That left him with a final score of 10.5. He then wandered off to play blitz and only checked back occasionally to see how his rival Reshevsky was doing. 
     Going into the last round Reshevsky had 9.5 and playing white, he needed to defeat William Lombardy to tie Fischer. That was not outside the realm of possibility, but when the dust had settled, Lombardy had won the Championship for Fischer by defeating Reshevsky. 
 
     Did that mean Bobby Fischer was the best player in the United States? When asked, he said, "No, one tournament doesn't mean much." Who was the best? "Maybe Reshevsky..." Things soon changed, didn't they? 
     In the following game Reshevsky defeats Arthur Bisguier in one of those games that looks so simple that playing like him looks like it would be a fairly easy thing to do.

A Slugfest In Palestine

 
     In the chess world, 1939 started off with Laszlo Szabo winning at Hastings. Later, in the spring, an international tournament was held at Margate and it was won by Paul Keres ahead of Jose Capablanca and Salo Flohr. 
     The USSR Chess Championship, held in Leningrad, was won Mikhail Botvinnik. The American Chess Federation (ACF) championship (aka the U.S. Open) was held in New York and was won by Reuben Fine ahead of Samuel Reshevsky and I.A. Horowitz. 
     The Chess Olympiad (known at the time as the Hamilton-Russell Cup) and Women’s World Championship was held in Buenos Aires, Argentina. Germany won followed by Poland s and Estonia. Vera Menchik-Stevenson won the Women’s World Championship. 
     On September 1, the day the finals commenced, Germany invaded Poland, starting World War II and the English team returned home immediately. At the conclusion of events, many participants decided to stay in Argentina or moved elsewhere in South America, rather than face an uncertain future by returning to a Europe in the midst of war. Among them were all five members of the German team (Eliskases, Michel, Engels, Becker, Reinhardt). 
     Finally, at the end of the year the American Chess Federation and the National Chess Federation formed the United States Chess Federation. 
     There was no nation of Israel and in Palestine, Britain's military and diplomatic efforts brought the Arab Rebellion, which had started in 1935, to an end in the late summer of 1939. 
     The following slugfest, that is probably the best word you could use for such a game as Winz-Czerniak, was played in the Palestine championship. It was a game in which attack and defense changed hands and ingenious sacrifices were countered by even more ingenious ones. 
     It looked like black could have resigned after 13.Rxa7, but Czerniak kept fighting and eventually prevailed at the end by avoiding a shrewd attempt by his opponent to set up a stalemate. 
     Viktor Winz (1896-?) was a Palestine/Israeli–Argentine master. He was born in Germany and began his career in Berlin. He emigrated to Palestine (then under the British Mandate) in the early 1930s. Winz played for the Palestine team in three Olympiads (1934, 1935 and 1939. When World War II broke out during the 1939 Olympiad Winz remained in Argentina permanently. 
     Moshe Czerniak (1910-1984) was a Polish-Israeli International Master. Czerniak emigrated from Poland to Israel in 1934. And, like his opponent, after the 1939 Olympiad he also decided to remain in Argentina. He returned to Israel in 1950.

An Instructional Tactical Game

     In his writings that exceptional teacher C.J.S. Purdy reminded readers to always comb the board for tactics after your opponent moves. And, before making your own move you should visualize the new position for tactics. 
     If you don’t ask yourself if your opponent has any threats, you will constantly be making blunders. Likewise, if you don't look for tactical threat before you move, you will constantly miss them. There’s no point in strategic planning when there’s a winning combination in the position. 
     As Teichmann once put it, chess is 99 per cent tactics, but after playing on some servers I have come to the conclusion that a lot of amateur players have no idea what tactics are. They seem to think that just willy-nilly sacrificing a piece or making a bad move for the sake of a vague "threat" is playing tactically. 
     They play like the guy I played several games against online the other day. He insisted on plying 1.e5 and 2.Qh5; sure Nakamura has played it in Blitz, but he's a Super-GM. My opponent also liked to play Bf4 and Bxf7+ or Nf3, Ng5 and Nxf7.
     We had a little conversation between moves and when I asked him about it, his comment was that he wins a lot of games by playing tactically. He wasn't playing tactically, he was blundering. 
     Another opponent who was badgering me and using a lot of profanity stated he was an "opening innovator." When I replied that there is a difference between an opening innovation and a bad move, it elicited a string of cuss words. I took great pleasure in gloating over beating him a couple of times. 
     The point is that there is a difference between playing tactically and giving away a piece for nothing. Purdy always emphasized sound tactics. I am discounting Tal-like, risky, unclear sacrifices because most of us are not as good as he was and can't calculate like he did. 
     The way you find tactics is not looking at the position and trying various moves until you find something that works. If you see one or more of these things, there is a possibility that a tactical solution exists: 
 
1. Look at all checks. 
2. Look for undefended pieces. 
3. Look for pins and forks. 
4. Look for pieces (especially the King!) that do not have any escape squares. 
5. Look for masked pieces (i.e. pieces on the same line) 
6. Look for pieces that may be performing more than one defensive task 
7. Finally, briefly look at bizarre and surprising moves, sacrifices, Pawn breaks and “obviously unplayable” moves. 
 
     More often than not, there won't be a sound tactic available, but only after you have ascertained that there isn't should you proceed with your strategical plan, assuming you have one...a lot of amateurs don't. 
     Back in my day positional play was emphasized and tactics were a neglected area. Today it's the other way around, or at least it seems that way. During a game, especially in complicated, unclear positions, you have to be extremely attentive otherwise unpleasant surprises will await you. 
     No matter how good a strategical plan might be, a tactical mistake will completely ruin it. That's a problem with chess...it may take 40 moves to win, but only one bad one to lose. 
     The following short, but highly instructive game, played by two Moscow masters demonstrates some general ideas typical of the middlegame and a clash of two strategical plans. 
     White, relying on his lead in development, concentrated his pieces in the center and prepared an attack on the black King that was not castled. Black sacrificed a Pawn hoping for a counterattack on the Q-side where white was castled. 
     The game was decided by a Queen sacrifice when in final mating attack saw all the white pieces taking part. Yuri Averbakh described the action: 
 
1. The R on d1 took away the black K's squares on the d-file and defended the N at d8. 
2. The N, in tum, deprived the K of f7 square, the B deprived the K of f6
3. The R on e1 landed the fatal blow. 
 
While all that was happening, for black's part...
 
1. His B on f8 and P on f6 not only failed to help, they actually hinder the K's escape. 
2. The rest of black's pieces were cheerless spectators in the execution of their own monarch. 
 
     The winner, Mikhail Bronch-Osmolovsky (1919-1975) was awarded the Soviet National Master title in 1951. He is known for his contributions to opening theory and as a Soviet arbiter and President of the central chess section of the Burivyestnik Club. Nothing is known of his opponent, Boris Baranov (1923-1976).

A Lesson On Connected Passed Pawns

     One of my early instructional books that I probably gained the most from was Ludek Pachman's classic, Modern Chess Strategy. In the book's section on passed Pawns, he wrote that two united passed Pawns are a dangerous weapon, but the possessor of such Pawns must make sure that they cannot be blockaded and that, as a rule, such Pawns should advance together
     Pachman gave the following game as an illustration of what happens if the Pawns are blockaded. In the final position white's connected passed Pawns on the Q-side went nowhere while black's connected passed Pawns in the center marched to victory. 
     When Pachman gave this as a model game he left the reader with the impression that Gligoric's opening strategy was completely faulty and, a a result, it was doomed from the beginning. But, thanks to Stockfish and Komodo it is clear that that was not the case. 
     In fact, the opening line as late as move 18 was played in at least four later games and white won them all, so clearly black's position after 17....Ne8 actually favors white slightly as is indicated by Stockfish and Komodo. Based on the evidence then, it's clear that Gligoric's loss must be attributed to a later error and not faulty opening strategy. 
     Still, the game is a good example of the principle that two united passed Pawns should not be allowed to be blockaded as Gligoric allowed to happen in this game and its instructional value is not diminished.

Keres' Classic Sacrifice on f7

     The 6th (1935) Olympiad was organized by the FIDE and consisted of an open team tournament and an unofficial women's tournament as well as several events designed to promote the chess. It took place between August 16 and August 31, 1935, in Warsaw, Poland. 
     The Olympiad witnessed the debut of some strong young players: Paul Keres, Gideon Stahlberg, Jacobo Bolbochan, Andrea Lilienthal, Erich Eliskases, Peter rifunovic, Arthur Dake and Laszlo Szabo, among others. 
     At the start, the favorites were the United States (Reuben Fine, Frank Marshall, Abraham Kupchik, Arthur Dake and I.A. Horowitz) and Czechoslovakia, mostly because of their board 1 player, Salo Flohr, at the time one of the strongest world players in the world. The final standings out of 20 teams was 1) United States 2) Sweden and 3) Poland. 
     The Unites States' third consecutive win of this event was mainly credited to Arthur Dake's outstanding 15.5-2.5 score. An interesting sidelight was that although Dake was born in Portland, Oregon, his father was from Poland and so Dake refused to play against Poland. Kupchik went undefeated and that was also a great help. 
     It was at this event that Paul Keres (January 7, 1916 - June 5, 1975) was introduced to the world; he met World Champion Alexander Alekhine, Savielly Tartakower and SaloFlohr. He lost to all three of them, but scored a respectable 12-7. 
     In the following game his opponent, William Winter (September 11, 1898 - December 18, 1955), was an interesting character who was British Champion in 1935 and 1936. Winter spent six months in prison for sedition (conduct or speech inciting people to rebel against the authority of a state or monarch) due to his communist activity. 
     Before castling, the weakest squares on the board are f2 for white and f7 for black. In this game Keres' assault on f7 with a N sacrifice in the opening is not only entertaining, but instructive. 
     In the game Keres demonstrates the principle that a sacrificial attack on f7 (or f2), whether with a Bishop or a Knight, must be followed up by aggressive action. That's because after ...Kxf7 not only can the King not castle, it is exposed to attack and there is also a weakness on the diagonal d1-h5. Any advantage white gets is generally of a transitory nature and must be energetically exploited before it disappears.

A Bad Day Online

     Last Friday morning was spent running errands and in the afternoon I spent some time playing Blitz on Chess Hotel. It was a bad day...I was going to say a lot of good players were on line, but a more accurate way of putting it was a lot of players better than me were on line. There's a difference. 
     I lost several games and of the two I won, one was a seesaw affair where my opponent ran out of time in a winning position...at least Stockfish said it was winning. 
     The following game was the most interesting. I blundered away a P at move 3, but somehow managed to get compensation for it. Playing Blitz online is one thing, but in OTB play I agree with GM Alex Yermolinsky when he states that even average players should play solid mainline openings and avoid all that nonsense some titled players use to sell books...stuff like making your opponent think on his own, etc. If I play a wacky opening I have to think on my own, too, and experience tells me that thinking on my own doesn't always work out too well.
     Going back to my OTB days, I realized that average players rarely played more than 6-8 "book" moves in any opening anyway and so a deep study was a waste of time. 
     In one game my opponent was snapping out his opening moves at a Blitz pace while I was using quite a bit of time. Then all of a sudden I played a move and he sank into thought for several minutes and I knew we were at the end of what he had memorized. His reply was a weak move that soon left him totally lost. 
     In the postmortem I got schooled on the whole variation (of a Sicilian, I think it was). When we got to the move that made him think, I was told my move was bad (and maybe it was) because it wasn't what Fischer played. My question to him was, if it was such a bad move why couldn't he refute it? 
     In any case, in this game even though I lost the d-Pawn on move 3 Komodo 14 only gives black an advantage of about half a Pawn. It makes me think we amateur players put way too much emphasis on openings and our time might be better spent studying other aspects of the game.

Viktor the Terrible Tears Up Tal

     The year 1962 started of with Botvinnik winning the annual Hastings Christmas tournament and pocketing $280 (worth about 10 times that today).
     Chessplayers lost that year were Vyacheslav Ragozin, Ernst Gruenfeld, Czech IM Josef Rejfir, Milan Vidmar, Ossip Bernstein and Frank Graves, a former USCF president. 
     On October 25, 1962, the strong US Senior Master 38-year old Abe Turner was stabbed to death in the offices of Chess Review by Theodore Smith, an ex-mental patient. Turner was stabbed in the back 9 times and then his 280 pound body stuffed in a large safe. 
     The Stockholm Interzonal was won by 18-year-old Bobby Fischer who was undefeated. Tigran Petrosian won the Candidates tournament at Curacao. US representatives Bobby Fischer and Pal Benko finished 4th and 6th (out of 8 places) respectively. After the tournament Fischer accused the Russians of cheating by rigging the outcome of their games; later Korchnoi confirmed the accusations. 
     The following game was played in the 1962 Soviet Championship. The tournament, which had been preceded by six semifinals events, was held from November 21 to December 20 in Yerevan, the capital and largest city of Armenia. Korchnoi scored +10 -1 =8, losing only to Vladas Mikenas. Curiously, Mikenas defeated both Korchnoi and Tal. 
     The following game has been widely published and was included by Korchnoi in his own best games collection. While referring to notes by GM John Emms, GM Andy Soltis and USCF Life Master A.J. Goldsby, and with the help of Stockfish 15, Komodo 14, I have tried to weed out a lot of variations, including some erroneous analysis, and just capture the essence of this struggle between these two leviathans of the chess world. Enjoy the game! 

A game that I liked (Komodo 14)

Nc3 exd5 5. cxd5 d6 6. Nf3 g6 {At the time Tal was almost the only titled player that played the sharp Benoni and he was responsible for its surge in popularity. Black plays for a Q-side attack while white tries to use his center Ps.} 7. g3 {A Korchnoi favorite.} Bg7 8. Bg2 O-O 9. O-O Na6 {At the time this move was all the rage; today either 9...a6 or 9...Re8, or sometimes 9...Nbd7 are the standard moves. In the book of his best games Korchnoi slapped a ? on the move, but it's quite playable.} 10. h3 {An important part of white's strategy. He wants to advance his center Ps, but first prevents black from playing ....Bg5 and ...Bxf3 thereby getting rid of his bad B. An alternative is 10.Nd2} Nc7 { GM John Emms disapproved of this move blaming it for black's opening problems, claiming that 10...Re8 in order to hinder white's center advance makes more sense. Komodo doesn't see much difference between the two moves.} (10... Re8 11. Nd2 Nc7 12. a4 b6 13. e4 Ba6 14. Re1 Nd7 15. Nf3 Qe7 16. Bf4 Qf8 {with equal chances.

Stockfish drops its evaluation to 2. 5 Ps in white's favor, but Komodo 14 is much less harsh, favoring white by only one P. In any case, Tal's temperament would not permit a passive defense.} 19. e5 {Korchnoi breaks through in the center in classic fashion and quickly develops a K-side attack.} dxe5 20.
